I can't change to a new character's route! I finishes Neil's story and wanted to move on, but every time I try to choose somebody else and come back out of the menu it is stuck on Neil chapter 28. Help??
That's because only one other character besides Neil is available, which is Dimitri. And currently, only his first 7 chapters are available.
The other characters aren't released yet :)
You can get early access to Dimitri's most updated route (which is at chapters 1 - 23 at the moment), through the Patreon.
